To all whom amaycgn ems v; y v

Be it known that LGnone KmKEeAAnn, a citizen of the United States, and a resident of the city of New .York," i'n the county of New York and State of New York, United States of America; 'have' invented certain new and useful 1m rovements in HeadsfonIBottle- Cappin esi f which, th f l w is a speci cation. I

My 'nvention relates; to headsffor' bottle cappin machines and its object is to provide a simp e device which will bef inore'efiicient than those now in'use;

I will 'describemy inventioninthe follow ing specification and point out the novel features thereof in claims.

Referringto the drawings, Figurel is a side elevation of a head for abottle capping machine made accordin to my invention. Fig. 2 isya sectional e elevation of the same device. *Fig. 3 is aplan view and Fig.

4 isan inverted plan viewi of'the device "shown in Figs. land 2. Figs. 5 and 6 are,

that when they are placed together. they form a circular head or die. The outer sur bottom of the grooves 31.

respectively, a'side elevation and a plan view of-a bottle stop er which I have invented andwhich is ful y described in Letters Patent No. 829,341, issued tome under date of August 21st, 1906.- t

1 Like characters of reference designate corresponding parts inall of the figures? .10- designates ahead or die fo a machine used for applyingbottle stoppers to bottles.

This head-comprises three 1parts 20, 30 and 40 which are substantialy alike. These threeparts are sectors of a circular body so faces of this die may be'pro'vi'ded with a series of parallel ooves 31. A spring 32 is arranged to be p aced in one'of these grooves, or a lurality of such. springs may be used if desired. All these springs-are'preferably constructed of spring steel or brass-wire of circular cross-section and are in the form of a circular ring split at 33, the inner diameter of which is somewhat less than that of the When laced u on a head these springs not only ho d the t ee sectors of the head together but also serve the purpose of holding them in horizontal alinement. I sometimes provide springs made of difierent sizes of wire for use in conjunction with this head in order to vary the tension under which these parts are held together and can use one or more of such springs according to the work to which the head is to'be ap lied. The inner su ace of the head is provided with cam shaped grooves such as 35. This groove has a cross-sectional shape designed to fit ov'er lugs and projections on the bottle cap or stopper with which it is designed to be used an which will be described herein- 'ar'ter. Each of the groov'esis vertically inclined so that its distance from the central axis of the head is greater at the bottomof the head than it is at the top of the head.-

I prefer to make the lower part 36 of this incline at a greater angle from the vertical than is the upper portion 37. Each of the diameter of the head is of suificient size to Patented Dec. 10, 1907."

10 j three sectors 1s provided with a groove sirm- I lar. to that whichis described. The inside allow the head to pass over the bottle stopper with which it is to be used.

A pin 34 is shown in one of the sectors. This pin may be provided for the purpose of preventingh the head from rotating in the press or ot er machinein which 'it is used.'

At 50, in Figs 5 and 6, is shown a bottle stripper which Ihave invented and which I wi now briefly describes It comprises a 1 disk portion 51 having an annulardep'ending flange 52 integral w' t 53, 53 of sufficient length to enga e,with the neck of a bottle to whlch it is to' e applied, and a third finger 54 similar to the othersbut considerably lon er.

which are two fingers These-fingers are pro-Y vided as shown, or example at 55,.with projecting ribs for the pur ose of stiflening and strengthening the bott e cap structure. In

applying these-ca s or stoppersto the neck o a bottle a pac ing is first placed within the disk portion of the-cap which is then placed upon the neck. of a bottle with the three fingers slightly spread a art. The

over the ca 50. This head is es eci lower portion of the head 10 is t enapllaepd' signed for t e cap above describe inthis case I fit over the fingers 53 and 54. The shape of the grooves is such that they will not crushand the cam-shaped grooves are arranged to the projecting ribs such as 55 and the indntations 38 are provided for this purpose.

The head is then pressed down over the cap and the neck of the bottle by any suitab e means. A steep incline oi-the lower part ofthe grooves, such as 36, will cause the first part of this movement to press the three fingers of the cap quickly inward against the its,

I head under bottle, when the upper part, such as 37, of the grooves will come in contact with the fingers. A further downward movement of the pressure will cause the fingers to be pushed in against the bottle .with great force causing the cap, because of the eculiar construction of its fingers and the s ape of the'neck of the bottle, to be firmly locked to the bottle. Heretofore, heads similar in shape to the one herein shown and described have been used for this purpose. It has been found that when such heads are used, if the re ssure upon the heads is too great, or if the head is pushed downtoo far, or if a bottle with a neck slightly larger than others is used the neck will be'crushed and the bottle destroyed, unless means are provided for rendering them yieldable. In the present invention this difficulty is overcome for, as soon as the pressure becomes excessive for any cause, the head itself will expand against the action of the spring or springs 32 which may be as heavy or as light as desired. facilitate the operation of applying caps to the necks of bottles as the operation may be made with greater certainty and at a much higher rate of speed and entirely without the costly breakage caused by the solid heads heretofore used.

In illustrating my invention I have shown a bottle stopper which I have invented and a head for capping machines which is designed to be used with this articular stopper. It is obvious that the principle of this invention may be embodied in other forms of bottle capping heads and that the heads may be deslgnedto be used in conjunction with other bottle stoppers of this class.

What I claim is.

1. A plurality of sectors together forming a hollow circular die, the inner surface of said die being arranged to coact with parts of a bottle stopper cap, a horizontal groove on the outer surfaces of said sectors, and aspring in said groove arranged to hold said sectors together.

2. A plurality of sectors together forming a hollow circular die, the inner surfaces of said die being arranged to coact with parts of a bottle stopper cap, horizontal grooves on the outer surfaces of said sectors, and s )lit rings in said horizontal grooves arrangerl to yieldably hold said sectors together.

3. A plurality of sectors, together fOIIDlD" a hollow circular die, said die being arrange to be used in conjunction with a bottle stopper cap, horizontal grooves on the outer surfaces of said sectors, a cam-shaped groove on the inner surface of each of said sectors, said grooves being arranged to coact with parts of said cap, and sprin s in the horizontal grooves arranged to yie dably hold said sectors together and to hold the sectors in horizontal alinement.

4. A plurality of, sectors, together forming a hollow circular die, said die being arranged to be used in conjunction with a bottle stopper cap, horizontal grooves on the outer surfaces of said sectors, a cam-sha ed groove on the inner surface of each of said sectors, said grooves being arranged to coact with parts of said cap, and provided with indentations for clearing other parts of the cap, and springs in the horizontal grooves arranged to yieldably hold said sectors together and to hold the sectors in horizontal alinement.

5. A plurality of sectors together forming a hollow circular die, said die being arranged to be used in conjunction with a bottle stopper cap, horizontal grooves on the outer surfaces of said sectors, a cam-shaped groove on the inner surface of each of said sectors, saidgrooves having two parts at different angles from the axis of the die and arranged to coact with parts of said cap, and being provided with indentations for clearing other parts of the cap, andsplit rings in the horizontal grooves arranged to yieldably hold said sectors together and to hold the sectors in horizontal alinement.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
